Business

If a business was a human beign, brand would be its personality, its soul.
Advertising (communication) is it's appearance, discourse.
Its suppliers is its meal - they're filling it with energy neccesary to produce customers.
Customers are its children - because the 'purpose of the business is to create customer' (Peter F. Drucker), it is the sacred goal of the business - create and serve by the means of business processes, educate through advertising its kids - CUSTOMERS.
